I IMPROVEMENT IN GAS COCKS AND VALVES.

Specification forming part of Letters Patent No. 178,759, dated J nne13, 1876 application filed February 9, 1876.

To all whom it may concern:

Be it known that I, CHARLES A. GERDEN- IER, of Bridgeport, Fairfieldcounty, Connecticut, have invented certain new and useful Improvementsin Gas Cocks or Valves, of which the following is a specification:

My invention relates to cocks or valves for regnhfiing the flow of gasto burners of that class adapted to be operated by a torch or implement;and itsprime object is so to attach an arm or lever to the key of thevalve that it is limited in its movement, when actuated for turning onor shutting off the gas, without the aid of the usual pin-stop, whichsoon wears out and causes the valve to leak.

The manner of carrying out my invention and the subject-matter claimedwill hereinafter specifically be set forth.

In the accompanying drawings, Figure 1 is a view in elevation ofmyimprovements; Fig. 2, a side view; and Fig. 3, a vertical centralsection on the line or a; of Fig. 2.

The shell or casing A of the cook or valve may be of any of the usualwell-known forms, and is provided with a tubular portion, a, forming aprolongation of the key-seat. This tubular portion is recessed or cutaway, at a, forabout half its circumference, for the reception, and toallow of sufficient play, of an actuating arm or lever, B, secured toitin any suitable way, or formingpart of the key C of the valve, and bywhich the key is actuated in turning on or. shutting off the flow of gasto the burners. The actuating-arm B is provided on its free end withsuitable bearing-surfaces for the operating torch, and has also formedon its base shoulders I), which limit its movement, when actuated forturning on or shutting off the gas, by coming in contact with theshoulders formed by the recess in which it works.

This construction hasbeen found to possess great advantages over thewell-known pinstop heretofore employed.

The key C of the valve is shown as conical or tapering in form, itsbearings in the casingbeing correspondingly shaped, and is provided -onits end opposite to that carrying the actu-. ating-arm with aspring-washer, D, compressed between-a shoulder on the casing and asetscrew, or its equivalent, on the end of thekey, the tendency of whichis always to draw the key tighter and compensatefo'r any wear of theparts, whereby a tight joint is preserved, and all leakage of gasavoided.

My improvements are shown as applied to the shell or support of anordinary street-lamp burner, to which they are especially adapted, as bytheir use all climbing of the post may be dispensed with, the operatorlighting the lamp by a suitable torch from the sidewalk.

My improvements will be found of great advantage in all cases whereburners are located at such a distance as to require a torch or im- Iplement to operate the cock. I claim as my invention- The improved gascook or valve, substantially as hereinbefore set forth, consisting ofthe combination of the casing, the key turning therein, its actuatingarmworking in-a recessed portion of the casing, and provided withbearing-surfaces on its free end, and the compensating-spring, wherebythe range of movement of the actuating-arm is limited and wear of thekey compensated.

In testimony whereof I have hereunto subscribed my name.

CHARLES A. GERDENIER.
